Chelsea have conceded 57 goals in the Premier League this season – their worst ever total in the goals-against column in the history of the competition.
These numbers will make damning reading for Blues manager Mauricio Pochettino, who is arguably doing an even worse job than Graham Potter and caretaker manager Frank Lampard did last season.
Arsenal thrashed Chelsea 5-0 at the Emirates Stadium last night, with Leandro Trossard scoring early, while even Ben White grabbed a brace, and Kai Havertz picked up two against his old club.
